Technical Data


Sandwich ELISA, Biotin-labelled antibody


BioVendor’s AChRAb ELISA depends on the ability of AChRAb in human serum to bind to similar sites on the AChR as various monoclonal antibodies such as MAb1 (coated on ELISA plate wells) and/or MAb2 and/or MAb3 (which are labelled with Biotin).

Research topic



The BioVendor Acetylcholine Receptor Autoantibody (AChRAb) ELISA kit is intended for use by professional persons only, for the quantitative determination of AChRAb in human serum. Autoantibodies to the acetylcholine receptor (AChR) are responsible for failure of the neuromuscular junction in myasthenia gravis. Measurement of these antibodies can be of considerable value in disease diagnosis and management.
